I don't want to stop your cheering, but that isn't a perfect solution either.

That is unfortunately most like a bug in the BIOS.
What happens here is when you specify acpi=off that the internal Vega M gets
disabled and the address space that one used freed up.
This address space is then used for the Thunderbolt Controller to handle the
Polaris.
What you could try is to blacklist amdgpu from automatically loading and then
issue the following commands as root manually:
#Disable the internal Vega M
echo 1 > ./bus/pci/devices/0000:01:00.0/remove
#Manually load amdgpu to initialize the Polaris
modprobe amdgpu
#Rescan the PCI bus to find the Vega M again
echo 1 > ./bus/pci/devices/0000:00:00.0/rescan
It's just a shot into the dark, but that might work as well.
Apart from that there isn't much else you could do except to upgrade the BIOS
or use different hardware.
